Method for the detection of visual function losses

A method for detecting visual function losses, comprising:

• a) carrying out an exploration of an anterior segment and an intraocular media of an eye of a patient and determining, based on a result of said exploration, that both the anterior segment and the intraocular media of said eye are healthy;
• b) carrying out an optical quality analysis on at least one retinal image of said eye having a healthy anterior segment and healthy intraocular media as determined in step a) or from information related to said retinal image, wherein said optical quality analysis comprises analyzing the contents related to intraocular scattering and aberrations or to just intraocular scattering based on said retinal image, whereby the calculation of an objective scatter index, OSI, resulting from the relationship between the light energy found in a peripheral area of the retina plane image (Eext) and the light energy found in a central area thereof (Ec), according to the expression:
• OSI
• =
• E
• ext
• E
• c
• is considered as a parameter indicative of optical quality;
• and
• c) obtaining an indication of a functional aetiological or pathological visual function loss of the visual system depending on a result of said calculated OSI parameter.
